Abstract—Embedded intelligence can help controlling and reducing the energy consumption of appliances to a significant amount. Such a smart appliance will consist of a communication interface, a local processing and decision unit and the appliance’s actual function. Sophisticated functions for such a device will involve a notion of real-time with a respective time format, a generic database that contains energy usage logs, error messages, warnings and real-time measurements for power usage, and an embedded self-description that allows to integrate the device into a system with minimum manual configuration. While there exists concepts for smart plugs and smart outlets that can be applied to “smarten ” an existing device, in general we need to assume that the variety of appliances and technologies will require the support for various architectures including software solutions that integrate into the functions of an appliance with existing computing power, e.g. a DVD player or a state-of-theart television set. Thus there is a need for architectural services with flexibility for different hosting systems while keeping the interoperability with respect to a smart home control system.

ABSTRACT Smart grid, envisioned as an indispensable power infrastructure, is featured by real-time and two-way communications. How to securely retrieve and audit the communicated metering data for validation testing is, however, still challenging for smart grid. In this paper, we propose a novel privacy-preserving range query (PaRQ) scheme over encrypted metering data to address the privacy issues in financial auditing for smart grid. Our PaRQ allows a residential user to store metering data on a cloud server in an encrypted form. When financial auditing is needed, an authorized requester can send its range query tokens to the cloud server to retrieve the metering data. Specifically, the PaRQ constructs a hidden vector encryption based range query predicate to encrypt the searchable attributes and session keys of the encrypted data. Meanwhile, the requester’s range query can be transferred into two query tokens, which are used to find the matched query results. Security analysis demonstrates that in the PaRQ, only the authorized requesters can obtain the query results, while the data confidentiality and query privacy are also preserved. The simulation results show that

Today’s electricity grid was designed and constructed to meet the requirements in the last century. The grid is primarily radial, built for centralized power generation, and is dependent on manual restoration. In addition, reliability of traditional electric grid is ensured mainly by having excessive power capacity in the whole system, with one-way power flow from power plants to consumers. Although lots of newly-developed information and communication technologies have dramatically affected the other industry sectors, the

Original scientific paper This paper is an effort towards constructing a comprehensive model for the smart grid as a network of networks with the ability of evaluating events in presence of every smart grid feature. To this end, the network modelling laws are employed to attain a proper structure for the model, the automata theory is used to explain the performance of the proposed model, and the hybrid function theory is utilized to define an appropriate mathematical description for it. By evaluating the smart grid cooperative processes, and determining the role of special smart grid features in these processes, a six-layered hierarchical structure is chosen. Each layer of this structure is considered as an automaton and its autonomous performance is described by a hybrid function, mathematically. The composition of these six hybrid functions introduces the final formulation of the model. To verify the suitability of the proposed
